Help! I lost my audio.

I recently updated my SB and installed a new router (old one died) and now I cannot hear anything from my SB Duet.

Controller Firmware 7.7.2 r9663
Receiver Firmware 77
Netgear R6300 Router
Squeezecenter Version ? not sure what this is or where to find it.... i have the logitech media server up and running on my desktop

Connections:

I have SB Duet Ethernet connected to my router
I have a vortexbox holding all of my music Ethernet connected to my router
I use wifi for the SB controller

When I log into my router I can see the vortexbox & squeezebox attached via 'wired connections'
I can also see the squeezebox controller attached via "wireless connections"

I can find all of my music files, playlists, internet radio, pandora, etc. on my controller. When I start the music on the controller the little arrow moves forward as if it is playing. But there is no sound from my speakers. I have attached the SB to another audio output, still no sound. I can use the Logitech Media Server web browser program and it does the exact same thing.

any input????
